PIPE-FITTING.

Specification of Letters Patent.

Patented Sept. 5, 1916.

Application filed October 18, 1915. Serial No. 56,465.

To all whom it may concern Be it known that I, LOUIS W. PoLrrsKY, acitizen of the United States, and resident of Boston, in the county ofSuffolk and State of Massachusetts, have invented new and usefulImprovements in Pipe-Fittings, of which the following is aspecification.

This invention relates to soil pipe fittings, and consists in a fitting)having a main soil pipe and an integral ranch or branches, of novel andimproved form, all as hereinafter more fully described, and particularlypointed out in the claims.

In the accompanying drawing whlch lllustrates certain embodiments of theinvention, Figure 1 is a perspective view of one form of pipe fittingcontaining the invention; Fig. 2 is a plan view of said fitt1ng; F1g. 3is a front elevation of said fitting; F 1g. 4 1s a side elevation ofsaid fitting; Fig. 5 is a front elevation of a modified form of fitting;Fig. 6 is a plan view, and Fig 7 is a front elevation, of the fittingshown in Fig. 5.

Referring first to Figs. 1 to 4: The fitting comprises a vertical mainsoil pipe at, which is designed to be inserted into and form a part of acontinuous main soil pipe or stack a (Fig. 3) which extends verticallythrough the several stories of a building. The stack a may contain asimilar pipe fitting on each floor. 6 is a closet branch or bendextending forwardly and upwardly from the main soil pipe at, integraltherewith, and adapted for connection to a closet in the usual way. 0 isa laterally extending soil branch integral with and opening into theforward side of the main soil pipe a, adapted for connection to a bowlor similar fixture, the waste from which is to discharge into the mainsoil pipe. The branch 0 extends from the forward side of the main soilpipe forwardly a little, and then rearwardly, forming a bend adapted toadmit a vertical vent pipe (Z between and in the same plane as the mainsoil pipe and the free end of the branch 0, which terminates beside themain soil pipe. Thus when the fitting is placed in position adjacent toa wall W, the main pipe a, the vent pipe d and the end of branch 0, areall in a line practically parallelwith and close to the wall, and astraight upright vent stack, 0?, may be used extending through theseveral floors of the building, without using costly and unsightlyfixtures to carry the vent stack around the branch soil pipe as isnecessary when a Y of usual construction is used. The closet bend 6preferably has a vertical enlargement 7) near its junction with the mainsoil pipe, and a vent branch 6, formed integral with the fitting, opensinto the top of the enlarged portion 6 of the closet bend, and extendstherefrom laterally and rearwardly to a position between and in linewith the end of the branch 0, and the main soil pipe at. Said ventbranch 6 is spaced apart from the end of the branch soil pipe 0 toprovide a space for the vertically extending vent pipe (Z, by a suitableconnection such as an elbow or quarter-turn 6. Thus the branch soilpipe, vent branch and vent pipe are all brought into alined position atthe side of the main soil pipe, close to and parallel with the wall.

In the modification shown in Figs. 5 to 7, a fitting is shown having nocloset bend or vent branch, but designed for connection to a single bowlor other fixture. The main soil pipe c is adapted, as before, to beinserted in a main upright stack; and the laterally extending branchsoil pipe, formed integral with the main soil pipe, extends forwardlyand then bends rearwardly to a position at the side of the main soilpipe, so as to admit a vent pipe d in line with the main soil pipe andthe free end of the branch 0.

I claim:

1. An integral pipe-fitting comprising a vertical main soil-pipe and acloset-branch leading upwardly and forwardly therefrom, said branchhaving integral therewith an upwardly extending forwardly offset lateral soil branch taking into the lower part of said closet-branch andterminating in a portion ofiset rearwardly to define with said mainsoil-pipe a plane, with respect to which plan said lateral branchprovides a soil branch adapting a vertical vent or other pipe or pipesin the said plane to be jumped or bridged over by said soil branch; anda vent-pipe branch opening from the upper portion of said closet branchand extending toward said plane, whereby a straight ventpipe in saidplane may be employed to ventilate all of the connections to saidsoil-pipe.

2. A pipe fitting comprising a vertical main soil pipe, a closet branchextending forwardly from the main soil pipe and made integral therewith,a laterally extending branch opening into the main soil pipe and -littleand then rearwardly to a position at position at the same side of themain soil pipe as said first branch, said two branches being spacedapart to admit a vertically eX- 10 tending pipe between them.

made integral therewith, constituting a branch soil pipe, and bendingforwardly a one side of the main soil pipe, and a second branch openinginto the upper part of the closet branch and constituting a vent, saidsecond branch also bending rearwardly to a
